My idea

I'm a new user to stackoverflow and I'm loving the usage of tags to filter questions. This feature is really good because of the huge amount of information the users post dialy, however I've found out that is somewhat tedious to filter each tag I don't want to see.

I mean taking into consideration the fact that SO has around 24.150 tags and 227,182 questions it's just A LOT of information.

So how about instead of having to write the tags on the sidebar or the user profile we add small icons to the tags?

This would allow faster navigation and make it a lot simpler for users to understand and use SO. Allowing faster filtering and navigation to improve the user experience.

Here's a little example of what I'm talking about:

This way you can filter everything way faster than using the sidebar, thus improving the user experience and allowing the users to focus on the information they really need.

I've personally found typing the few tags into the list fairly easy to do. I probably ignore or find interesting about 40 tags. I would support a drag and drop idea, but the icons add quite a bit of noise.

Think of how often you'd actually want to add or remove tags from/to your lists. After just a few weeks, most of the work will be done. But then, the additional icons are not used anymore and just take up screen real estate.
